I have a roll of tape like that it the basement, laying on a new HE furnace I had put in about 20 years ago, but wasn't this discussion about a thin but refractory and safe to handle, insulation material? On an ender3, even 1/4" is going to drag on the beam the table spider runs on if put on the bottom of the suspension spider. Taking the plate off the spider and interposing a thin insulator would use the spider frame to retain it, and I need to do that anyway since the factory assembly puts a twist in that power cable that needs untwisted to keep it from looping around the bed adjusting knob on that corner. So whatever we stick on the bottom of the table spider, should have a non-wearing bottom surface. Above it, trapped between the spider and the bed, would be much less of a problem. Thr longer cool down at the end of the job might get bothersome though. I've considered mounting a fan on the overhead bar, facing down, switching it on when the bed moves forward at the end of the job with another 'home" switch on the front end of the beam, so it blows down on the plate to hasten the cooling, > > On Monday, September 7, 2020, 12:50:49 PM MDT, Gene Heskett > <ghesk...@shentel.net> wrote: > > On Sunday 06 September 2020 23:37:46 Gregg Eshelman via Emc-users wrote: > > Look for Kaowool.

That idea the whole printer could just sit on. But that might overheat the controller box too, so I'd druther not. > > Looks like it may be unobtainium on this local real estate.
